摘要：

In this paper , the present situation of secondary system grounding in substation is comprehensively analyzed, some improvement measures are put forward, such as perfecting setting of secondary grounding grid, improving anti-interference ability of secondary equipment, canceling insulated copper bar in cabinet, making clear grounding mode of cable shielding layer, increasing protection of the weak electrical signal cable, have solved the problem of grounding frequently occurring in engineering.
